Spectrophobia
Spectrophobia (from Latin: spectrum, n. specio, an appearance, form, image of a thing; an apparition, spectre) or catoptrophobia (from Greek κάτοπτρον kátoptron, "mirror") is a kind of specific phobia involving a morbid fear of mirrors. This phobia is distinct from eisoptrophobia, which is the fear of one's own reflection.
